Not sure but if I read the rules correctly I think you don't need to add a electric fuel pump but if you have one its needs a kill switch on it. What I have done in the past with the same setup as 722 is used a electric solenoid to turn the fuel on and off on the injection pump. When you turn on your key this energize the solenoid turning on injector fuel (instead of a cable). Wire the kill switch in the circuit so if it gets pulled this will kill power to solenoid killing engine. Along with a air shut off to intake as Mike spoke of.
